“Adam is fantastic. He has incredible subject matter expertise, but he is also practical and savvy.”
— Chambers USA 2026
Adam Baas is a Chambers-ranked litigator with more than two decades of experience in high-stakes product liability, toxic tort and environmental litigation. He has established himself as one of the country’s leading litigators in matters involving emerging contaminants in air, water and sediment.
Throughout his notable career, Adam has developed unique knowledge litigating complex environmental matters across the U.S. concerning PFAS, benzene, MTBE, ethylene oxide, 6PPD and dioxin. His broad practice encompasses state attorney general actions seeking natural resource damages under environmental statutes and novel product liability theories, as well as defending citizen suits under a variety of environmental laws – including completing a trial recently in federal court surrounding the use of 6PPD in tires.
Adam has been at the forefront of PFAS litigation for nearly a decade, leading discussions nationwide on the evolving state of the law and science surrounding these compounds. He has defended actions alleging PFAS contamination and exposure in both state and federal court, including multidistrict litigation and putative class actions – including playing an important role in the national litigation surrounding PFAS historically present in firefighting foam.
Over the course of more than 20 years in state and federal courts, Adam has served as lead counsel representing corporate clients in a wide range of complex multi-plaintiff matters. He brings extensive experience navigating locally managed mass torts in state court and national multidistrict litigation in federal court. His collaborative work with the nation's leading experts in toxicology, chemistry, hydrology and epidemiology provides his clients with a decisive advantage in complex scientific litigation.
Beyond litigation, Adam routinely assists clients in identifying and mitigating future risks related to emerging contaminants. His advisory practice includes counseling on regulatory compliance with state and federal environmental laws, representing companies in the remediation, purchase and sale of contaminated properties, negotiating access agreements and reviewing environmental aspects of real estate transactions.
